人为的土地利用已经不可逆转地改变了人类赖以生存的自然系统。遥感技术的进步使人们更好地了解社会和经济进程在何处、为何以及如何推动全球重要的土地利用变化，从砍伐森林到城市化。然而，在土地变化分析中往往没有考虑非法活动的作用。由于缺乏未记录的、有意隐藏的交易数据，因此很难将这些数据纳入对土地变化的具体空间分析。我们提出了非法土地交易的概念框架和双管齐下的方法，利用遥感数据将非法活动与土地使用在空间上联系起来。
Anthropogenic land use has irrevocably transformed the natural systems on which humankind relies. Advances in remote sensing have led to an improved understanding of where, why and how social and economic processes drive globally important land-use changes, from deforestation to urbanization. The role of illicit activities, however, is often absent in land change analysis. The paucity of data on unrecorded, intentionally hidden transactions makes them difficult to incorporate into spatially specific analyses of land change. We present a conceptual framework of illicit land transactions and a two-pronged approach using remotely sensed data to spatially link illicit activities to land uses.
